Specification of Letters Patent.

Patented Aug. 17, 1915.

Application filed May 9, 1914. Serial No. 837,963.

To all whom it may concern Be it known that 1, LEE Roy APPLEGATE, acitizen of the United States, and resident of Seattle, King county,'Washington, have invented certain new and useful Improvements in Pumps,of which the following is a specification.

shown my invention embodied in the form which is now preferred by me.

Figure 1 is a front elevation of the pump showing one end thereof invertical section. Fig. 2 is an end elevation showing the base and aportion of one cylinder in section. Fig. 3 shows one of the valves inperspective. Fig. 4 is a central transverse sectional elevation. thecranks and pistons being omitted. Fig. 5 is a plan view of the base,with portions of the valve chamber covering plates removed, and with thecylinders in place. Fig. 6 is a bottom plan view of the plate whichengages the upper ends of the cylinders.

The base 1 contains therein a series of transverse channels 10, thenumber of'which corresponds with the number of cylinders used in thepump. Each of these channels has an upwardly extending opening 11designed to communicate with the cylinder which is employed inconnection therewith. The upper surface, of the casing surrounding theseopenings is slightly recessed to form a ledge 9 which receives andsupports the lower end of its cylinder 3. The cylinders are preferablymade as plain tubular shells.

At each side of the casing channels are formed connecting all of thetransverse channels 10. The channel 18 at one side of the casingconstitutes an inlet header from which the water is supplied to all thetransverse channels 10. The channel 13 which is at the opposite side ofthe base communicates with the opposite ends of all the channels 10,and. constitutes the discharge header. Between the connection with thecylinder and the inlet header each transverse channel 10 is providedwith a chamber 12 which extends upwardly to the upper surface of thebase and constitutes a valve chamber. In this chamber is placed a valve2 which is adapted to close the port 19 which connects channel 10 withthe inlet header 18. In the wall of the casing lying between the valvechamber 12 and the inlet header 18 is formed a slot of T-shape,extending from the upper surface of the casing downward to a point closeto the port 19. This slot is made with the stem of the T communicatingwith the valve chamber 12. The valve which is used is shown inperspectivein Fig. 3. This consists of a plate 2, of a size and shape tosatisfactorily close the port 19, provided at its upper edge with acurved or elbow-shaped arm 20, havingat its end a transverse bar 21,which arm and head are adapted to enter the T-shaped slot 22. At theopposite end of the transverse channel 10 the port 1 1 whichcommunicates with the discharge header 13 is closed by a valve of thesame construction and mounting. An inlet and outlet valve of thischaracter is provided for each of the transverse channels 10.

The inlet header 18 and the valve chambers 12 are closed at their upperside by a plate 15 which is bolted down thereon, and the outlet header13 is closed in a similar manner by a plate 16. Plate 16 is providedwith an opening for the reception of the discharge pipe 8.

A standard 5 is secured ateach end of the base, and extends upwardly,providing hearing 61 for the crank shaft 6. This standard has a crossbar 50 located at a point approximating in level to that of the upperends of cylinders 3, preferably being slightly lower than the ends ofthe cylinders. A plate 4, shown in bottom plan View in Fig. 6, isprovided with openings 40 having recesses 11 in the lower surface of theplate adapted to receive the upper ends of the cylinders 3. This platehas ends 12 which project between the side bars of the standard 5 andover the cross bar 50, to which the plate is bolted so as to be drawnstrongly down upon the ends of the cylinders.

Where several cylinders are used, as shown in the drawings, centralholding-down bars 4% should be employed, these passing through the plateand being anchored in the base 1. lhese bolts may also be employedto-hold down a short standard 52, which contains a central bearing 62for the crank shaft.

The crank shaft 6 is provided With a series of cranks 60, one for eachcylinder, upon the bearings of which are journaled the connecting rods31, the other ends of these rods being pivoted in the pistons 30. Thiscrank shaft may also be provided With a shell 63, or any other suitablemeans for turning the same.

The construction above described is one Whichis very simple and cheap tomake, and one which is easily maintained in good Working condition. Thetype of valve employed is one Which provides a large opening With asmall movement, is cheap to make, and Will close quickly.

What I claim as my invention and desire to patent is:

I l. A multiple cylinder pump having a baseprovided With a series ofshallow, cylinder-seating recesses arranged in a central row, a seriesof Water conduits extending transversely of said roW of cylinder seatingrecesses, one below and communicating With each cylinder seating recess,a valve controllingeach end of each of said transverseconduits, theupper Walls of said conduits 'hav-.

ing openings over and giving access to each of said valves, said basehaving header channels connecting the ends of sand transverse conduitsand provided With means for connecting with supply and discharge pipes,and plates for closing the openings into said channels: 1

2. A multiple cylinder pump comprising-a base .hav-ingsupply anddischarge ports therein and an alined roW of cylinder seating recessesin its upper surface, each communicating With a separate port, a seriesof plain tubular cylinders lacking end closures, each seating in one ofthe said recesses, a platehaving a corresponding series of alinedcylinder seating recesses placedupon the upper end of the cylinders andhaving holes therethrough communicating With the cylinder bores, andtension bolts connecting said plate With the base. 7 i

3. A multiple cylinder pump comprising a base'having supply anddischarge ports therein and an alined row of cylinder seat ing recessesin its upper surface, each communicating With a separate port, a seriesof plain tubular cylinders lacking end closures,

each seating in one of the said recesses, a plate having a correspondingSEHQSVOI? alined cylinder seating recesses placed upon the upper end ofthecyhnders and havlng holes therethrough communicating with the cylbase havingsupply and discharge ports and. controllingvalves thereinand, having an alined row of cylinder seating recesses in its upper faceand openings connecting each of said cylinder seats'with its respectiveports in the base, a series-of cylinders each con sisting of a' plaintubular shell fitted, each to its respectlve seat, a standard extendingupward from the base at each end of the row of cylinders, and providedWith a shaft bearing at its upper end and a ledge at a levelcorresponding-to the upper ends; of the cylinders, a plate havingcylinder jcentering and holding means extending over the row of.cylinders and having holes therein correspondingwvith the cylinderbores,

the ends of said plate being clamped down upon the ledges ofthe endstandards, tension bolts connecting the central portion of saidplatewiththe base, and a shaft bearing member supported from the saidplate andsecured bysaid tension bolts. I

5. A pump having a base provided With a channel communicating With thepump cylinder and at each side of this connection having a valve chamberextendingupvvardly and opening at the upper surface of the base, oneside vvall of said chamberconsth tuting a valve seat, said Wall, abovethe port therethrough, having a T-shaped recess extending from the uppersurface of the 7 base downward With the'base ofzthe open ing into-thevalvechamber, and valves each having an elbow-shaped central armterminating in a transverse bar adapted to fit'into' the recess in thechamberWall, and plates closing the upper opening'of said chamber.

In testimony whereof I have hereunto aflixed my signature. this 1st. dayof May, 1914;. 1
